IMPROVED FORGING-HMMER.

The Schedulev referred to in 'these' Letters Patent and making part of the same.

To all '1thom it may concern.:

Be lit known that` I, SAMUEL. B. DODGE, of Roslyn, in the county of Queens, and State of New York, have invented, made, and applied to use, a certain new and useful Improvement in l `orging-Ha1rnners;,and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this speciiication, wherein- Figure 1 is a pian of the. said machine complete, and

Figure 2 is aside elevation of thesame.

Similar letters denote thc same parts,l 1

The object of this invention is to furnish a forginghammer that can be worked by hand much more ell fectively and with less labor than the ordinary sledgehammer, andthe same machine can be run by steam 0r other power, when that is available, thus making a machine that can be empleyedY in either large or smal l smitherics.

My invent-ion consist-s in a hammer, mounted so that its fnl'crum can he adj usted vertically to keep the face ofthe hammelparallel to the anvil at any desired distance, in combination witha spring-colmection to a crank-pin, that can be adjusted, and so that the revolution ofthe crank-pin shall operate the hammer with a blow similar to that given by thc human arm, and said yielding connection between the hammer and crank-pin, allows for the different thicknesses of material being forged.

1n the drawingais the frame, carrying the shafts ofthe drivingpulley b, and c is a wheel, to which a clank-handle 'is applied, so that the` machine can be driven by hand or by power. n

c' is a belt to the pulley tl, on the shaft c, and f is a tightening-pulley, operated by the treadle y, so that the belt can be allowed to slip more or less, and thereby the speed of the blows of the hammer be regu-l lated.

On the end of the shaft e is a disk or face-plate, h, carrying the crank-pin i. This may be moved. into either of the holes 1 2, in the said disk h, Yso as to regulate the extent of movement given to the hammerk. i

The handle I, of the hammer, is provided at its back end wit-h a broadplate or disk, l', that occupies a slot4 in the vertical standard m, and through these thelful-l Crum-pin or bolt 3, 'of the hammer, passes, l

This construction prevents the hammer tilting sideivisc, and keeps the face ot' the hammer parallel with that ofthe anvil n, transversely.

At the top and bottom of the standard m are thel be shod with iron plates to prevent wear.

. The rconnection, from the crank-pin to the gh'ammer 1.1,' is through the adjustable link rr and spring s.

This link fr can be lengthened or shortened as occasion may require, and the blow being communicated through the spring s, the parts/yieldto the=gi=eater thicknessof metal, when the hammering of the samecommences. y y

By this construction of hammer, the attendant has the entire control of the blow, to make it heavier or lighter, more or less rapid, and the hammercau bev driven by manual or other power.

Shaping-dies may be applied to the hammer or anvil, or both, thus greatly increasing the usefnlnessof this hammer over the ordinary Sledge.

What I claim, and desire to secure by Letters Patent, s

The flagging-hammer, provided with the standard m, carrying the fulcrum, and adjustable, as set'forth, in combination with the revolving crank-pin i, adj ustable link r, spring s, hammer Jr, and anvil n, as and for the purposes specified. y

In witness whereof, Ihave hereunto set my signature, this 15th day of April, 1869.

Witnesses: SAMUEL B. DODGE.
